Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a schematic view of a scene of network monitoring along a railway according to an embodiment of the present invention, and as shown in fig. 1, a private network coverage scheme is adopted for a network along a railway, that is, private network cells, such as a private network cell 1, a private network cell 2, a private network cell 3, and a private network cell 4, are established along a railway. Under normal conditions, when a user takes a railway, the user can switch among the private network cells according to the railway traveling direction. When the user uses the private railway network, the cells occupied at different times have a fixed sequence, and a switching sequence can be formed. For example: when the train is traveling in the traveling direction in fig. 1, the switching sequence of the user is: private network cell 1, private network cell 2, private network cell 3 and private network cell 4; when the traveling direction of the train is opposite to the traveling direction in fig. 1, the switching sequence of the user is: private network cell 4, private network cell 3, private network cell 2 and private network cell 1. When the actual cell switching sequence of the railway user is different from the standard cell switching sequence, it indicates that the wireless network covering the railway is abnormal, thereby affecting the communication quality of the user.
In the prior art, an alarm monitoring method is generally adopted for monitoring a wireless network of a railway, but the alarm monitoring method can only find problems such as hardware faults and the like, but cannot acquire the actual wireless network condition of the position of a user. According to the method for monitoring the network along the railway, provided by the embodiment of the invention, the standard cell switching sequence is obtained based on the engineering parameters of the cells along the railway and the historical cell switching sequence of the railway user, and then whether the network along the railway is abnormal or not is determined by comparing the actual cell switching sequence of the railway user with the standard cell switching sequence, so that the problems of the network along the railway can be truly reflected according to the actual switching sequence of the user.
The technical solution of the present invention will be described in detail below with specific examples. These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a flowchart of a method for monitoring a network along a railway according to an embodiment of the present invention, as shown in fig. 2, the method of this embodiment may include:
s201: acquiring engineering parameters of cells along a railway and a cell switching sequence of railway users; the cell switching sequence comprises a historical cell switching sequence of the railway user and an actual cell switching sequence of the railway user; the engineering parameters of the railway line cells comprise the engineering parameters of the railway private network cells and the engineering parameters of the public network cells.
In this embodiment, a cell is an area unit in mobile communication management, and a communication network may be divided into many areas according to the coverage area of an antenna, where a user can use the network for communication. Base stations can be established at regular intervals along the railway, and circles obtained by taking the base stations as circle centers and covering distances as radii are cells formed by the base stations.
In order to obtain the switching sequence of the standard cells along the railway, engineering parameters of the cells along the railway are obtained first, and the switching sequence of each cell can be obtained according to the engineering parameters of each cell. The engineering parameters of the railway line cells acquired by the method not only comprise the engineering parameters of the railway private network cells, but also comprise the engineering parameters of the railway peripheral public network cells. This is because, for various reasons such as geographical location, it may not be allowed to establish a private railway network cell at a certain location, and in order to ensure normal communication of a railway user, it is necessary to migrate the communication of the user to a public network cell closest to the user. For example, the handover sequences of the cells are private network cell 1, private network cell 2, private network cell 3 according to the engineering parameters of the cells, and there is public network cell 1.
In this embodiment, a cell switching sequence of the railway user needs to be obtained, where the cell switching sequence of the railway user needs to include a historical cell switching sequence of the railway user, and a sequence of each cell actually used by the user in a normal network state can be obtained by obtaining the historical cell switching sequence of the railway user. The cell handover sequences obtained based on the engineering parameters can be adjusted by historical cell handover sequences.
In addition, the cell switching sequence of the railway user also comprises the actual cell switching sequence of the railway user. Whether the network along the current railway is abnormal or not can be judged through the actual cell switching sequence.
S202: and determining a standard cell switching sequence according to the engineering parameters of the cells along the railway and the historical cell switching sequence of the railway user.
In this embodiment, after the cell switching sequence obtained based on the engineering parameters of the cells along the railway is obtained, only the theoretical switching sequence is obtained, but the wireless environment itself is complex and changes frequently, so that the cell switching sequence obtained based on the engineering parameters of the cells along the railway needs to be corrected. And comparing the historical cell switching sequence of the railway user with the cell switching sequence obtained based on the engineering parameters of the cells along the railway to obtain a standard cell switching sequence. For example: when the switching sequence of the cell is obtained as a private network cell 1, a private network cell 2 and a private network cell 3 according to the engineering parameters of the cell and a public network cell 1 exists, and when the acquired historical cell switching sequence of the railway user is the private network cell 1, the private network cell 2, the public network cell 1 and the private network cell 3, the standard cell switching sequence can be considered as the private network cell 1, the private network cell 2, the public network cell 1 and the private network cell 3.
The method comprises the steps of obtaining a standard cell switching sequence by combining a cell switching sequence obtained based on engineering parameters of cells along a railway with a historical cell switching sequence of a railway user, and enabling the obtained standard cell switching sequence to be an accurate cell switching sequence. The cell switching sequence obtained only by depending on the engineering parameters of the cells along the railway is only a theoretical switching sequence, and has larger errors. The cell switching sequence obtained by only adopting the historical cell switching sequence of the railway user lacks theoretical basis, and the obtained result has no accuracy.
S203: and determining whether the network along the railway is abnormal or not according to the actual cell switching sequence of the railway user and the standard cell switching sequence.
And after the actual cell switching sequence of the railway user is obtained, comparing the actual cell switching sequence of the railway user with the standard cell switching sequence. If the comparison result shows that the two sequences are consistent, the network along the railway is normal; and if the comparison result shows that the two sequences are inconsistent, the network along the railway is abnormal.
In the embodiment, the standard cell switching sequence is obtained according to the engineering parameters of the cells along the railway and the historical cell switching sequence of the railway user, the obtained standard cell switching sequence can truly reflect the switching sequence of the railway wireless network, and whether the network along the railway is abnormal or not is determined by comparing the actual cell switching sequence of the railway user with the standard cell switching sequence. Furthermore, compared with the prior art, the method has the advantages of simple data acquisition and data analysis and short time consumption.
Optionally, the determining the network state along the railway according to the actual cell switching sequence of the railway user and the standard cell switching sequence includes at least one of the following:
for each user, if a network cell which is not included in a standard cell switching sequence appears in an actual cell switching sequence corresponding to the user, determining that the user is an over-range switching user; and if the ratio of the number of the users which are switched out of the range to the total number of the plurality of users to be analyzed is larger than a first user ratio threshold, determining that the railway private network cell is abnormal or the public network cell is abnormal.
For each user, if the actual cell switching sequence corresponding to the user has cross-network cell switching, determining that the user is a cross-network switching user; and if the ratio of the number of the users switched across the network to the total number of the plurality of users to be analyzed is greater than a second user ratio threshold, determining that the railway private network cell is abnormal.
For each user, if the round-trip switching occurs in the actual cell switching sequence corresponding to the user, determining that the user is the round-trip switching user; and if the ratio of the number of the users switched back and forth to the total number of the plurality of users to be analyzed is greater than a third user ratio threshold, determining that the coverage area of the railway private network cell is abnormal.
After the actual cell switching sequence of the user is obtained, the actual cell switching sequence is compared with the standard cell switching sequence, and whether the network along the railway is abnormal or not can be obtained according to the comparison result. The comparison result may include three types: network cells which are not contained in the standard cell switching sequence appear in the actual cell switching sequence; the actual cell switching sequence is switched across network cells; and, a round-trip handover occurs in the actual cell handover sequence. The following is a description of the above three types of abnormal switching.
Fig. 3 is a schematic diagram of an out-of-range handover occurring in an actual cell handover sequence provided by the present invention, as shown in fig. 3, in a certain road segment, when a standard cell handover sequence is a handover sequence of a private network cell 1, a private network cell 2, a private network cell 3, and a private network cell 4, and a user passes through the road segment, and the actual handover sequence is a handover sequence of the private network cell 1, a public network cell 1, the private network cell 3, and the private network cell 4, it indicates that the user has the out-of-range handover. When determining whether the network state is abnormal, acquiring a plurality of user sample data to be analyzed, and when the ratio of the number of users who are switched out of range to the total number of the plurality of users to be analyzed is greater than a first user ratio threshold, indicating that the network of the road section is abnormal. Specifically, the network abnormal condition may be that the peripheral public network cell 1 is adjusted, which affects the signal of the private network cell 2; or, the private network cell 2 has a fault, and the user communicates through the public network cell 1.
When the above abnormality of the road section is determined, a large number of users are required to meet the over-range switching condition. For example, if there is an out-of-range handover of 80% of users, it indicates that the abnormal condition occurs in the road segment.
Fig. 4 is an exemplary diagram of cross-network cell handover occurring in an actual cell handover sequence provided by the present invention, as shown in fig. 4, in a certain road segment, when a standard cell handover sequence is a handover sequence of a private network cell 1, a private network cell 2, a private network cell 3, and a private network cell 4, and a user passes through the road segment, and the actual handover sequence is a handover sequence of the private network cell 1 to the private network cell 4, it indicates that the user has cross-network handover. And when the ratio of the number of the users switched across the network to the total number of the plurality of users to be analyzed is greater than a second user proportion threshold, the network of the road section is abnormal. The second user ratio threshold is a preset value, and may be the same as the first user ratio threshold or different from the first user ratio threshold, for example, the second user ratio threshold may be 80% or 85%.
When the user is switched across networks, the network abnormality of the road section may be that the railway private network cell is abnormal. For example, when the actual handover sequence of the user is private cell 1 to private cell 4, there is a possibility that private cell 2 and private cell 3 may fail.
Fig. 5 is a schematic diagram of a round-trip handover occurring in an actual cell handover sequence provided by the present invention, as shown in fig. 5, in a certain road segment, when a standard cell handover sequence is a handover sequence of a private network cell 1, a private network cell 2, a private network cell 3, and a private network cell 4, and a user passes through the road segment, when the actual handover sequence is a handover sequence of the private network cell 1, the private network cell 2, the private network cell 1, the private network cell 3, and the private network cell 1, it indicates that the round-trip handover occurs to the user. And when the ratio of the number of the users who switch back and forth to the total number of the plurality of users to be analyzed is larger than the third user proportion threshold, the network of the road section is abnormal. The third user ratio threshold may be the same as or different from the first user ratio threshold or the second user ratio threshold.
When the user is switched back and forth, the network anomaly of the road section may be that the private network cell has a handover coverage, or the overlapping coverage area of a part of cells is large. For example, when a round-trip handover occurs between private cell 1 and private cell 2, then the overlapping coverage area of the two cells is large.
Comparing the actual cell switching sequence of the user with the standard cell switching sequence, and when an abnormal condition occurs, indicating that the network of the road section is abnormal.
Fig. 6 is a flowchart of a method for monitoring a network along a railway according to a second embodiment of the present invention, as shown in fig. 6, on the basis of the first embodiment, a method for determining a standard cell switching sequence includes:
s601: acquiring a preset cell switching sequence according to engineering parameters of cells along a railway; the engineering parameters of the cells along the railway comprise at least one of the following: the cell identification code, the longitude and latitude of the cell, the antenna direction angle and the cell frequency point information.
In this embodiment, a handover sequence of a preset cell may be obtained according to an engineering parameter of the cell, and the handover sequence of the preset cell may be understood as a theoretical handover sequence. Wherein the engineering parameters of the cell can be obtained from a server of a communication operator. The Cell Identity (CI) is a code assigned by the network operator to all cells in the network. The cell latitude and longitude represents the location of the cell. The antenna direction angle is an angle of the antenna, and the difference of the antenna direction angles has a great influence on the communication network. The cell frequency point is the central frequency of the modulation signal. The basic information of the cell can be obtained through the engineering parameters of the cell.
S602: adjusting the switching sequence of the preset cell according to the historical cell switching sequence of the railway user, wherein the adjusted switching sequence of the preset cell is a standard cell switching sequence; the historical cell switching sequence of the railway user is a cell switching sequence under the normal condition of a wireless network.
In this embodiment, after obtaining the historical cell switching sequence of the railway user, the preset cell switching sequence is adjusted according to the historical cell switching sequence, for example, when the switching sequence of the preset cell is a private network cell 1, a private network cell 2, a private network cell 3, and there is a public network cell 1, and when the obtained historical cell switching sequence of the railway user is the private network cell 1, the private network cell 2, the public network cell 1, and the private network cell 3, the standard cell switching sequence is the private network cell 1, the private network cell 2, the public network cell 1, and the private network cell 3. It is easy to understand that when the historical cell switching sequences of a large number of railway users are the same switching sequence, the historical cell switching sequence can be used to adjust the switching sequence of the preset cell.
In this embodiment, the preset cell switching sequence obtained according to the engineering parameters of the cell is adjusted by using the historical cell switching sequence of the railway user, so that the obtained standard cell switching sequence is more accurate, and further, the result of whether the network along the railway is normal or not obtained according to the standard cell switching sequence is more accurate.
Optionally, the obtaining a preset cell switching sequence according to the engineering parameters of the cells along the railway includes: determining the information of the cells along the railway according to the engineering parameters of the cells along the railway; the information of the cells along the railway comprises: cell identity, cell location and cell coverage; and determining a preset cell switching sequence according to the information of the cells along the railway.
In this embodiment, a cell identifier can be identified by the cell identifier, the location of the cell can be obtained by the latitude and longitude of the cell, and the coverage area of the base station can be obtained by the antenna direction angle and the cell frequency point. After the information is obtained, a preset cell switching sequence can be obtained according to the cell identifier, the position of the cell and the coverage area.
For example, there are three private network cells in a certain road segment, and in a preset direction, the positions of the three private network cells are: private network district 1, private network district 2 and private network district 3, and the coverage of three district is first region, second area and third area respectively, then predetermine the district switching sequence and be: the private network cell 1 with the coverage range of the first area, the private network cell 2 with the coverage range of the second area and the private network cell 3 with the coverage range of the third area.
Optionally, the obtaining of the cell switching sequence of the railway user includes: determining a plurality of railway users to be analyzed, and acquiring signaling data of the plurality of railway users through a signaling monitoring platform; and determining a cell switching sequence of the railway user according to the signaling data.
In this embodiment, when a network condition of a certain road segment is to be detected, a railway user passing through the road segment is determined, and the railway user may be a user in multiple trains. The method can monitor the network of the common railway and the network of the high-speed rail, so that the user to be analyzed needs to be determined according to the type of the detected railway. When monitoring a network along a high-speed rail, a high-speed rail user needs to be determined first, and specifically, whether the user is on the high-speed rail can be determined according to the position and the speed of the railway user. Specifically, when the position of the user is in a preset road section and the speed of the user is in a preset speed range, the user is a high-speed rail user. For example, the predetermined speed range of the high-speed rail is 200 km/h to 250 km/h.
After a user to be analyzed is determined, signaling data of the user can be acquired through a signaling monitoring platform, the signaling data are transmission signals in a network, signaling can be transmitted among different links of the communication network, and each link is analyzed and processed. The cell switching sequence of the user on the road section can be obtained through the signaling data. For example: when signaling is transmitted between the private network cell 1 and the private network cell 2, it means that the cell switching sequence of the user is private network cell 1 to private network cell 2.
